A Rapid Mesh Fusion Method to Create 3D Virtual Characters in Games

With an increasing growth of games and animations, animators pay attention to design sophisticated 3D models with vast imagination, while 3D model constructions are a labor-extensive and time-consuming task. In this paper, we aim to reuse existing mesh models to reproduce a virtual character by means of the proposed mesh fusion method. In comparison with the conventional fusion methods, we tend to develop a rapid method instead of devising an off-line technology. The proposed method first selects two fragmented models that have been cut in advance by users, and integrates the mesh fragments into a complete model with little user interference. In order to associate the two mesh fragments with each other, a unit circle is used to project two open cutting boundaries on it; in addition, we take advantage of mesh morphing to generate a mesh patch in between the two open cutting boundaries and smooth the patch by using the Bezier interpolation. The experimental results show that the proposed method will be able to create a virtual character with an even in-between patch and a low time complexity.
